Answer:
$102
Step-by-step explanation:
The pay for the day of work is the total of morning hours worked and afternoon hours worked. In each case, the hours worked is the difference between the "Out" time and the "In" time.
morning hours = 12:15 -8:15 = 4:00
afternoon hours = 17:30 -13:00 = 4:30
total hours worked = morning hours + afternoon hours
total hours worked = 4:00 +4:30 = 8:30
This notation tells you (hours):(minutes). You know that 30 minutes is 1/2 hour, so the total time worked is 8 1/2 hours.
The pay is the product of the hours worked and the pay per hour:
pay = (8 1/2 hours) × ($12 /hour) = $102
Since 
and 
, we can rewrite the right side of the equation as
Using the identity 
, we can subtract 
from either side to obtain the identity 
substituting that into our previous expression, the right side of our equation simply becomes
We can now write our whole equation as
Adding 2 to both sides:
dividing both sides by 3:
When 0 ≤ x ≤ π, tan x can only be equal to 1 when sin x = cos x, which happens at x = π/4, and it can only be equal to -1 when -sin x = cos x, which happens at x = 3π/4
6/5 is equal to 1.2, so that is a rational number.
√2 is equal to 1.570796326794
... which is a irrational number.
so ur answer would be the top right answer choice.
hope i helped:)
